Gurley (75) proposes the following classification of the Myxosporidia : — 
I. Cryptocystes , n. ord. Myxosporidia , in which the pansporoblast 
produces many (at the fewest 8) spores ; the last minute, with- 
out distinct symmetry, with a single capsule ; type (and only) 
family : Qlugeidce , n. fam. 
II. Phccnocystes , n. ord. Myxosporidia, in which the pansporoblast 
produces few (at the most 2) spores; the last relatively large, 
with distinct symmetry and two or more capsules ; type family, 
Myxobolidce , ,n. fam. Other families : Cystodiscidce , Chloro- 
myxidce, Myxidiidce , n. fam.
